Letters Patent No. 95,038, dated September 21, 1869.

W mznoven MEAT-CUTTING- MACHINE.

The Schedule referred to in these Letters Patent and making part: or thesame.

To all whom it may concern.-

Be it known that I, Aueus'r N rr'rmenn, J r., of thecity and county ofPhiladelphia, and State of Pennsylvania, have invented a new and usefulImprovement in Meat-Cutting Machines; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing bad to the accompanying drawings, and to the letters, of referencemarked thereon.

This is an improvement on the meat-cutting machine patented by me, underdate of August 11, 1863, in which a rotary table or block is combinedwith reciprocating knives, and theJsaid knives so arranged on thecross-head that they can. be readily sharpened, and the edges preserved.I Mypres'ent improvement consists in securing on the inside of theframing triangular-shaped guides, so as to carry the cross-heads steadyand straight in their up-and-down movements; also,'h0lding the knives bya peculiar arrangement of spring-catches, so that they can be readilysharpened. The spring-catches also secure the guides in proper positionwhen the knives are in operation.

Figure 1 is a side elevationof my improvement, with a portion of thetable or' block-rim removed.

Figure 2 is an end elevation of same, with the knives turned intopositionready for sharpening.

To enable those skilled in the art to make and use my invention, I willnow proceed to describe its construction and operation.

Secured to the bed-plateB of the machine are two frames, F and F, whichare connected together at their upper ends, by means of the plate P.

Secured in the centre, and underneath the plate P, is an upright, U,which extends down within a short distance of the table or block 1.

The main driving-shalt S is formed with two cranks, O and G, whiclrworkin bearings E, E, and

Bearings E and E are secured to the interior and at the upper part ofthe franresh and F, and the.

bearing E is secured to the upright U, on a line with bearings E and EEn'circling each bolt which holds the caps of the bearings E,,E, and Ein place, are spiralsprings, A A A,flthe lower ends of which bear on thecaps, and the upper ends come in contact with the nuts placed vertheends of the bolts, so that in case any bones should be placed on theblock with the meat,

the sharp edges of the knives, in striking them, will cause the shaft toraise .inthe bearings, and thus act as a. cushion for the knives, andprevent their breaking or becoming dull. I

Connected to the cranks G and G are two r0ds, R and R", on the lowerends of whieh'are pivoted crossheads H and H, which work on and areguided in their up-and-down movements by triangular-shaped guides, G, G,G, and G, which are pivoted at their upper ends to the inner sides ofthe flames FandF', and to the sides of the upright U.

Guides G, G'LG, and-G are held in place by means of spring-catches K andK and reyolving-plate L. V

,The knives 1, 2, 3, and 4 are attached to and adjus'ted on thecross-heads H and H, in the usual manner. I

When it becomes necessary to sharpen the knives, the cross-headsare'turned until the knives assume ,a horizontal position, as showninfig.'2. In this posi-' tion they are retained by means of aspring-catch, K secured to the front of the frames E and F.

Having thus described my. invention, its construction and operation,

What I claim, and desire'to secure by Letters'Pat- 'ent of the United,States, is-

The arrangement ofthe upright U, triangular-shaped guides G, G G and G,spring-catches K, K, and K, and plate L,.substantially in the manner andfor the purpose specified.

In testimony whereof, I have hereunto signed'my name, in the presence oftwo subscribing witnesses.
